Subtag of test-equipment

Anything related to oscilloscopes (or "scopes", in EE jargon), a kind of electronic test instrument.

An oscilloscope is used to measure voltages and (with suitable probes) other physical quantities and to display their variations with time as curves on a screen. In other words, it's an instrument that allows to display the graphical representation of a signal as a function of time.

Q&A Is it always necessary to use the ground terminal of the oscilloscope probe?

Assume my oscilloscope is grounded, and the DUT is grounded as well (earth ground). I am using a standard 10 Mohm impedance 1:10 passive probe. So, the ground terminal of the probe is in fact con...

Q&A Siglent1104 oscilloscope channels lagging

First I noticed that clock begins before chipselect gets pulled low on SPI. After eliminating potential sources I started to suspect the scope. I connected all 4 channels to function generator at d...

Q&A What is sacrificed when buying cheaper oscilloscope probes (of same BW/cap/R/gain)

I'm wondering if there are particular aspects of an oscilloscope probe's performance that tend to suffer, or failure points to look out for, if/when buying lower-end makes of oscilloscope probes (l...
